Description

The THERMOLITE® Reactor Extreme liner is Sea to Summit’s warmest knitted sleeping bag liner. If your adventures take you to colder climates, the Reactor Extreme will add plenty of warmth to a sleeping bag. Plus in warmer weather, it can be used as a ‘stand alone’ sleeping bag. The hollow core fibres of the THERMOLITE® fabric work like a polar bear’s fur and, along with the knitted structure, trap plenty of insulating air. Super soft and amazingly stretchy, the Reactor Extreme uses a heavier version of THERMOLITE®  to provide extra warmth for an incredibly comfortable night’s sleep. Use one to build your cooler-weather sleep system and to help keep your sleeping bag clean too.

Features

  • Traps insulating air to increase warmth of a sleeping bag by up to 25°F / 15°C
  • Stretchy, Thermolite® fabric is incredibly comfortable.
  • 110g/m² fabric is warmer than the 80g/m² Thermolite® used in the standard Reactor.
  • Technical mummy-shape with drawstring hood.
  • Easy care – machine wash with no special soap needed. Avoid fabric softeners and dryer sheets.
  • Keeps sleeping bag clean.
  • Packs into its own Ultra-Sil stuff sack.

The Reactor Extreme is Perfect For

  • Backpackers whose sleep system will be used in colder climates
  • Campers whose sleeping bags don’t keep them warm a the advertised temperature
  • Very warm-weather campers who don’t need a full sleeping bag
  • Campers or backpackers looking to extend the performance of a (perhaps order) sleeping bag into shoulder seasons

 

Other Liner Options

  • The Reactor Fleece Liner will add even more warmth to your sleeping bag.
  • Performance-oriented, weight-focused end users may opt to use a Spark or Flame as a sleeping bag liner.
